Copying/renaming a file w/a date/time stamp

Question

Java virgin here.....
I am sure there is a post out here on this subject somewhere...
I am trying to rename a file using the date and time EG: MYFILE05031223.txt
Where 0503 is the date and 1223 is the time.
Thanks....

Thanks so much for your help...but seeing how I am a fullfledged newbie
perhaps you can assist as to why this code will not compile...
import java.io.*;
import java.util.*;
public class rename{ 
     public static boolean renameFile(File f) {                                                  
DateFormat df = new SimpleDateFormat("MMddHHmm");
     String timestamp = df.format(Calendar.getInstance().getTime());     
     return f.renameTo(new File("Barcoden" + timestamp + ".txt")); }
I am getting the following error msg's....
C:\jdk1.3.1_08\bin>javac c:\JavaCode\rename.java
c:\JavaCode\rename.java:17: cannot resolve symbol
symbol : class DateFormat
location: class rename
DateFormat df = new SimpleDateFormat("MMddHHmm");
